IMPROVED GAR-COUPLINGS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, DANIEL J. TITTLE, of the city and county of Albany,State of New York, have invented certain new and useful Improvements inCar-Couplings, and the mode of operating them; and .I do hereby declarethat the following is a full, clear, and exact descriptionthereof, ofits construction and operation, reference being had to the annexeddrawings, making a part of this specication," in which-'- Figure 1 is aperspective viewinverted. Y

Figure 2 is a view of draught-head secured.

Figure 8 isa cross-section view from beneath.

The same letters indicate like parts.

The nat-ure of my invention consists of constructing the draught-barwith a hing-e,.placed at any suitable point between the draw-beam andtheh'ead of the said draught-bar, whereby the head is rendered free to movein a lateral direction, while the end of the bar will be held rigid inthe drawLbeam. vTo ease the coupling-heads, when being detached, I placea lever against the back end of the draught-bar and connect with itslong en d a rodor chain, or both, whichis properly attached-to therack-wheel or segment-shaft, which shaft, when operated to throw thecoupling-heads aside, will also draw the lever against the end of thedraught-bar, and forceit forward and thereby ease the uncouplings. Toenable a person to uncouple the cars from the ground, I provide a leveron the 'under side of one of the outer beams of the car, one end ofwhich has a rack, which operates ina second rack provided-on the endofthe rack-bar, which, when pulled out, throws the coupling-head to oneside and at the same time operates the easing lever; To adapt cars ofvarying heights provided with the ordinary links for coupling with thecoupling of my invention,'I provide two or more slots4 horizontally cutin the ends of the double hook-heads, in either of which the links maybe inserted; and to serine the heads together rmly I make `in the headsan oblong hole, which r'uns down perpendicular through the whole depthof the head, and into one of these perpendicular holes I drop one leg ofbinding clevis, which is made U-shaped, while the other leg drops downback of the coupling-head or in the perpendicular hole ofthe co-actingcoupling-head. By these improvements cars can be as readily uncoupled bya person standing on the ground on the side of a car as when on theplatform, and when coupled can be secured frombeing disconnected whileturning a curve, as has been proved by actual test.; and cars withordinary coupling-links with varying heights can also be accommodated.

In the drawings, A, gs. 1 and 3, represents the under side of a platformor a car, to which thc coupling is attached. The draught-bar a `a ismade in two pieces and provided with a hinge, c, placed at any suitablepoint between the draw-beam and the double hook-head a', which permitsthe head to move in a lateral direction. Back of the draw-beam b, andagainst the end of the draught-bar a, is placed a lever, e, the shortend of which is held'by a suitable fulcrum,j`. This lever e has providedon its longest end a suitable eye, or its equivalent, to which isconnected a 'rod or chain,g, or both, which rod or chain is attached tothe rack-wheel or segmentshaft 8, which rack-wheel'shaf't, when turnedin either direction, throws the double hook-head d to one side; tud

at the same time draws, by the rod g, the lever e' against the end ofthe draught-bar a and throws` it forward,v -so that byboth the sideandforward movements of the double hook-heads (shown by the dotted linesd', fig. 3)

the cars can be nncoupled with ease. To uncouple cars without the aid ofthe hand-wheel, Iprovide on one of the side beams A of the car asuitable lever, la, which turns on a proper pivot. The short end of thislever terminates in a rack, L, which works another 'rack, z, on the endof shifting-bar k; and when' the long end of the lever is pulled out orpressed in the end rack /Loperates the shifting-bar 7c and throws thedouble headd to one side, and at thesame time operates the easing levere and throws the head forward the same as if the operation wereperformed by the rack-wheel shaft .sA To adapt my invention to theordinary links used in coupling, and/'to the varying heights of cars, Imake in the face of the double hook-headsfd two or more horizontal slotsm m. Into any of these slots the ordinary coupling-linksl can beinserted and secured by a suitable pin, as in the ordinary way; and toprevent the cars from uncoupling whenon a curve, &c., (as experiment hasshown they will do when no t secured,) I make a perpendicular hoie, n,through the whole' depth of the head d, through which I insert one legof the U-shaped clevis O, igs.`2 and 3,' and drop the other leg downback of the lread d,

or in asimilar hole, n', of a co-acting head.. Both legs of said clevisare made of suicient length to preclude all possibility of its jumpingout by :my jolting.

What I claim as my invention, and desire to -secure by Letters Patent,iis- 1. I claim the lever e, fulcrumf, and the rod or chain g, or both,in combination with the-rock-wheel shaft vs, as and for the purposedescribed.

.as and for the purposes set forth and described.

2. I claim the lever h, with the rack h ond the rack in combination withtheshifting-bar k, for the purpose set forth and described.

3. I claim the hinged'dreught-bai' a a, in combination with the lever e,`l'ulc'ruin f, rod and chain g, or both,

operated by the lever L or rack-wheel shaft s, as and for the purposesdescribed.

4. I claim the hook-head coupling perforated as described,v incombination with the clevis O, or its equivalent,v
